Please note: This table is not classed as surgical furniture.
Prior to and when adjusting the height of the table, make sure that no persons or objects are located in the
adjustment range of the table and that nobody has their hands on the underframe.
The following basically applies: Never reach into or under the frame of the table when adjusting the height.
Height adjustment can result in injury if the user does not pay due care and attention. Therefore, take great
care when performing this procedure.
When adjusting the upholstery parts, make sure that no persons or objects are in the adjustment range. Make
sure that no persons reach under the upholstery part or lean on the underframe.
Important for the user: When adjusting the upholstery parts, do not reach under the spacers located beneath
the upholstery parts.

Always use both hands when adjusting the lying surface elements: Use one hand to operate the adjustment
mechanism and the other hand for the lying surface adjustment.
The lying surfaces and the underframe are not anti-static as standard.
Our products are not intended for use in wet rooms and must under no circumstances be cleaned using so-
called bed washers. This would irreparably destroy the product.
The head part and armrests are only intended to support the patient and must not be used for sitting.
If the underframe is designed with movability (optional), all the castors must always be locked before using
the table.
Do not put a damaged device into operation.
Disconnect the device from the mains (power supply) in the event of a fault or during maintenance work.
To disconnect, be sure to grasp the plug, not the power cable.
This device must not be modified without the express permission of the manufacturer.
When transporting the table, take hold of the underframe, NOT the upper frame.
1.8 Model designation and type labelling

2. Operating manual
2.1 Table design
When designing the table frames, special emphasis was placed on functional and operational safety. The
number of possible pinching points has thus been minimised, while remaining ones have been covered or
protected with spacers to prevent injury, thus ensuring safe and yet simple operation. Nevertheless,
necessary caution must always be exercised when using the table.
The table consists of the following assemblies: - underframe, - scissor section, - upper frame, - upholstery.
Depending on the respective version, these assemblies can feature further attachment parts.
The surfaces of the welded design are plastic coated. The height adjustment unit is located between the
scissor sections or between the scissor section and the underframe, which guarantees very high power
transmission even in the lowest adjustment range (min. height). By extending or retracting the lifting tube, the
scissors are pushed apart or together, thus enabling adjustment of the lying surface. The electrical adjustment
system does not pose a hazard to the health and safety of the user or the patient when used as intended. The
lifting motor is activated by a low control voltage.
2.2 Height adjustment
Height adjustment (all models with electromotive height adjustment)
To adjust the height, the enclosed foot switch (optionally also hand switch) is operated according to the
marking. Beforehand, brief activation (double tap) must take place via the foot switch (or the hand switch).
Please refer to section 7. The table is lifted or lowered.
Height adjustment using foot switch rails (optional)
The electric motor for height adjustment is operated by a switch rail attached to the long side of the table,
which can be operated with your foot.
Press the switch rail down = the table is lifted. Lift the switch rail up = the table is lowered.
Here, too, brief activation (double tap) must take place beforehand (see section 7). Alternatively, the switch
rails can also be led out to the short side of the table. This facilitates height adjustment from the short sides of
the table. The lifting motor is equipped with a freewheeling clutch as standard. This ensures automatic
declutching if an obstacle is encountered when lowering. In other words, the active tractive force of the motor
no longer acts; instead, simply the weight of the upper part of the table is applied. In the event of unforeseen
entrapment, the risk of injury is significantly reduced.
Note on operation
The electric motor is to be operated in intermittent duty mode. This means that a maximum duty cycle
of 25 s must not be exceeded. Before switching the motor back on, an interruption time of at least 400
s must be observed. If the maximum duty cycle is exceeded, an internal thermal switch (protective
temperature limiter) in the motor interrupts the power supply to the actuator. After the electric motor
has cooled down, the thermal switch automatically reconnects the power supply to the actuator.
Height adjustment (all models with hydraulic height adjustment)
At tables equipped with hydraulic height adjustment, the height is adjusted by repeatedly depressing
(pumping) the foot lever on one side of the table. To lower the table, the foot lever is simply lifted with your
foot. If the table is only lifted slightly each time the foot lever is depressed after transport or a longer period of
non-use, air bubbles have formed in the hydraulic system. To remove the air bubbles, pump the table
upwards under load and perform an additional 20 - 30 strokes of the pump when the table is in the uppermost
position. This will force air out of the system.
2.3 Head part adjustment
Despite the very robust and strong design of the gas spring, the head part must not be used for
sitting!
Head part adjustment using a gas spring
The head part is adjusted using a gas spring. To operate, press the release lever, which is located at the end
of the head part underneath the upholstery part, in the direction of the upholstered surface. The head part is
